Résumé partiel
In the 21st century, sustainability has become an urgent concern for the construction industry worldwide. It has been seen as one of the most significant challenges at the present time. Nowadays, the theory of sustainability is considered as a central part of strategy changes in most parts of the world because of the likelihood of negative effects of particular practices on the environment and society. Whilst sustainability is receiving significant attention in construction companies in developed countries, this seems to be less true for the construction industry in developing countries.

This study explores the level to which the construction organisations in Libya scrutinise and employ viability assessments in construction activities, with a view to developing a strategy for transformation to improve sustainable practices. The study was carried out using a survey strategy to raise better understanding of the present status. A number of construction companies in Libya were selected for study to ensure the different backgrounds and opinions were included. The research was conducted in two phases ; first, a questionnaire survey was carried out to explore wide understandings of the existing practices and the desire of the participating companies to apply sustainable aspects in their practices. 134 completed questionnaires were analysed by using statistical techniques. The findings from the survey informed the topics for the interviews with 10 participants from the top and senior level management from Libyan construction companies. The interviews were prepared to obtain deep insights into the justification for the existing practices and perceived benefits, as well as the challenges and further recommendations. Interview data were analysed by using the content analysis method.

The outcomes of the research explained the adoption of sustainable construction in Libya, and the data showed that the awareness of sustainability in construction was weak in the practice of several companies. Weakness in awareness of sustainability was found to have been caused by low levels of understanding on the part of principal actors in the entire construction industry, such as the clients, regulatory and construction organisations. The behaviour of the stakeholders is essentially linked to their values, the nature of the construction industry and their sense of sustainability principles
